. SURGICAL APPLIANCE.

Specification of Letters Patent.

Patented May '18, 1920.

Application filed Maj 22, 1919, Serial No. 298,967. Renewed March 16, 1920. Serial No. 366,302.

To all whom it may covzcern:

Be it known thatI, LAFE O. Ronnnrs, a

citizen of the United States, and a resident, of Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Surgical Appliances, of which the following IS a specification. My invention is an improvement in surgical appliances, and has for its object to provide an appliance of thecharacter specified especially adapted fortying knots in l1ga-:

tures, in cavities where it is difiicult or impossible to reach with the hands.

In the drawings V Figure 1 is a perspective view of the improved appliance in use;

Fig. 2 is an enlarged perspective view of i the tying awe; and

Fig. 3 is a section on the line 33 of Fig.

2, looking in the direction of the arrows adjacent to the line.

The present embodiment of the invention comprises a pair of handles 1 and 2, which are pivotally connected as indicated at 3, the handle members being providedat one end with loops 1 for engagement by the fingers and at the other end with smooth plain j aws 5.

The pivotal connection between the members l and 2 is such that when the loops 4 are moved toward each other the jaws 5 will be moved away from each. other, and a plate spring 6 arranged between the members and secured to the member 1 acts normally to move the loops apart and the jaws 5 together.

A plate 7 is secured to the outer face of each of the jaws 5, each plate being held in place by ascrew 8 orthe like, and the said screw engages the plate at the inner end thereof. The outer end of each plate has an opening through which extends a pin 9 011 the ad acent jaw, the saidpins preventing swinging movement of the plates on the screw 8. Each plate has a laterally extending lip 10, the said lips extending in the same direction, and these lips overlie grooves 11 extending approximately longitudinally at the side of the jaw and at the side adja} cent to the lug 10. Referring to Fig. 1, it.

tying the first knot.

insert the hands. hemostatic forceps will be held by an assistwill be noted that the jaws 5 are bent ata'n Y members.

The improved appliance is used in con nectlon with ordinary hemostatic forceps indicated at 12. These forceps 12 are clamped 7 oblique angle with respect to the handle I 1.1, beneath the lugs 10, and there is sufiicient friction on the ligature to prevent slipping of the same when the loops of the handles are moved together to tie the ligature.

' 'In placing the ligature, with the first knot tied, as shown in Fig. 1, and the ends of the ligature beneath the plate'T, the said ends are drawn through until the ends of the jaws are close to the vessel, the looped ligature having been 'meanwhile slipped down upon the vessel. With the parts in this position the loops 4 are moved together, thus The second knot is tied, the ends of the ligature are again inserted beneath the plate 7 and the second knot is'tied in the same manner.

The improved device may be used many cavity where it is difficult or impossible to In tying the knots the ant.

I claim:

1. device of the character specified, comprising a pair of handle members pivoted together intermediate. their ends and provided at one end with grips, the pivotal connection being such that when the-grips are moved together the other ends of the handle members will be moved apart, a spring normally holding the grips apart, and a platesecured to the outer face of each handle member at the end remote from the grip, each plate being .resilient and forming aclamp cooperating with the handle mem her for gripping a ligature, each handle member having a groove lying obliquely beneath the outer end of the plate, and each plate having a lateral lug extending over the'groove for holding the ligature in place.

2. A device of the character specified,

comprising a pair of handle memberspivoted together intermediate their ends and provided at one end with grips, the pivotal connection being such that whenthe grips aremoved together the other ends otthe fhandle members will be moved aJart a spring normally holding the grips apart, and a plate secured to the outer face of each handle member at the end remote from the grip each plate being resilient and forming a clamp cooperating With the handle member for gripping a ligature.

3. A device for tying ligatures, comprising handle members pivoted together to move away from each other at one end 10 when they are pressed together at the other,

said handle members having grips at one end and gripping jaws at the other, normally in Contact with the said members, and resilient to yield therefrom when the ligature is forced beneath the jaws.
